INSEAM-TRIMMING MACHINE.

Specification of Letters Patent.

Patented Sept. 14, 1909.

To all whom it may concern:

Be it known that I, WILLIAM B. KEIGH- LEY, a citizen of the UnitedStates, residing in Vineland, New Jersey, have invented certainImprovements in Inseam- Trimming Machines, of which the following is aspecification.

One object of my invention is to provide a machine, capable of beingadvantageously used to trim the surplus leather and stock from theinseams of shoes at a certain point in their manufacture, which shall beof a relatively simple construction and at the same time substantial andreliable in operation.

Another object of the invention is to so arrange the parts of a machinehaving the above described characteristics that it shall occupy butrelatively little space, and be capable of being kept in operativecondition by the expenditure of a minimum of time and labor.

These objects and other advantageous ends I attain as hereinafter setforth, reference being bad to the accompanying drawings, in which Figure1, is a side elevation of my improved machine; Fig. 2, is a frontelevation of the device illustrated in Fig. 1, Figs. 3 and 4, aresections of portions of the cutting knife and its supporting wheelstructure, re-

' spectively illustrating the relative positions of the sharpeningwheels and the work supporting post, and Fig. 5, 1s a perspectlve Viewillustrating in detail the adjustable carriage structure for the worksupporting post.

During the manufacture of shoes of a certain type it is necessary at onestage of the operation to remove the surplus leather and stock from theinseam, and in order that this operation may be performed to a great eX-tent mechanically and that by a device of uncomplicated construction, Ihave provided the apparatus hereinafter described. This consists of asuitable supporting framework A provided with bearings a for a shaft Z)on which is mounted a pulley wheel 6 and a knife-carrying wheel B. Whilein the present instance I have shown these bearings a as formed inupwardly projecting standards, it is obvious that any desired type ofbearing may be employed to support the shaft 6.

Mounted upon the periphery of the wheel 13 is a knife 6 which inconstruction resembles a hoop, although, as shown in Fig. 3, it is soconstructed as to be part of a conical surface rather than of acylindrical surface; the circle of its cutting being of larger diameterthan that of its other edge. I do not confine myself to such form ofknife since I may use a cylindrical or flat form. This annular knife isheld to the wheel in any desired or suitable manner, in the presentinstance by screws 6 and its cutting edge is beveled as shown in Fig. 3.At the front of the machine is mounted the work supporting post D andwhile this may be of any construction suitable for holding a partlyfinished shoe so as to permit of its inseam being trimmed as desired, Ipreferably construct it as described and claimed in my application forpatent, No. 424,184, filed March 30, 1908, with modifications to suitthe present form of knife. It will be noted from Figs. 1 and 2 of thedrawings that this work supporting post D is so mounted upon the frame Aas to be movable both across the face of the knife and at right anglesthereto, and for this purpose is supported on a sliding carriage wherebyit may be moved toward and from the edge of the knife, parallel to theline of the shaft Z). This carriage is supported upon a second carriaged which may be moved at right angles to the first line of movement. Asshown in Fig. 1, the top face of the work supporting post B is inclinedor beveled in order that the material to be severed from the partlyfinished shoe may be supported in the most convenient manner.

In any suitable position relatively to the knife, I mount upon the frametwo brackets e and e which provide bearings for a pair of standards 6and e The first of these has an abrading wheel 6 so arranged that it maybe brought into contact with one of thecutting edges of the annularknife Z1 Upon the standard 6 is mounted a second abrading wheel 6 and italso is movable so that it may be brought into contact with the otherside of said knife. Each of these wheels has on its shaft a pulley wheelfor the reception of a driving belt connected to any suitable source ofpower.

Under operating conditions the knife supporting wheel B with its knifeis turned at a high velocity by a suitable belt acting on the pulley band the inseam of the shoe properly supported on the work post D may betrimmed to remove the surplus stock and leather as desired; said shoebeing free to be properly held and moved owing to the construction ofthe knife and work supporting post by which an unobstructedspace isprovided in front of the machine.

In order to prevent accidental contact with any part of the knife mountupon the frame protecting hoods or covers F and F which completelyinclose it except in the immediate vicinity of the two abrading wheels 0and e and at the front of the machine above thework supporting postwhere the said knife is necessarily exposed for a short distance, thoughit may, if desired, be provided with the finger guard shown and claimedin my above mentioned application for patent.

From the above description it will be noted that by providing an annularor endless knife mounted on the periphery of the wheel B so as toproject at one side thereof, the mechanism for trimming inseams as aboveindicated is reduced to. an exceedingly simple form, and is of. such 21natur tha the likelihoo dof its getting out of order or failing toproperly accomplish the work the face of the knife and at right anglesthere/t0, said post being adjacent to the ed of the knife. ,7
